Country of Origin may differ from what is shown above.
Black mustard seeds (Brassica nigra) are small, dark, intensely pungent seeds that are essential to Indian cooking and spice blends worldwide. These certified organic black mustard seeds have a sharp, hot flavour that develops when the seeds are crushed, ground, or tempered in hot oil. They are the traditional choice for tadka (tempering), where the seeds are popped in hot oil or ghee to release their nutty, spicy aroma before being added to dals, curries, and chutneys.
Key Benefits
- Essential Indian cooking spice: The classic seed for tadka (tempering), where black mustard seeds are popped in hot oil or ghee until they crackle. Used in dals, sambars, rasams, chutneys, and South Indian cooking.
- Hot, pungent flavour: Black mustard seeds are the hottest of the mustard varieties, delivering a sharp, wasabi-like heat when ground. The heat comes from sinigrin, a glucosinolate that converts to pungent allyl isothiocyanate.
- Pickling and preserving: A traditional ingredient in pickles, chutneys, and relishes. The whole seeds add texture and bursts of heat to preserved vegetables and fruit.
- Certified organic: Grown without synthetic pesticides or fertilisers.
Tadka (tempering): Heat oil or ghee in a small pan. Add 1 teaspoon of black mustard seeds and cover with a lid. When the seeds start to pop and crackle (about 30 seconds), add curry leaves and pour the sizzling mixture over dal, rice, or vegetables.
Spice blends: Grind black mustard seeds with Coriander Seed, cumin, and Turmeric for a homemade curry powder. Also used in pickling spice alongside Fennel Seed and peppercorns.
Homemade mustard: Soak black mustard seeds overnight, then blend with vinegar, salt, and honey for a fiery wholegrain mustard. Mix with yellow mustard seeds for a milder result.
The pungent heat of mustard seeds only develops when the seeds are broken and mixed with liquid. The enzyme myrosinase converts glucosinolates into the sharp isothiocyanates that give mustard its bite. Cold water produces the hottest result, while hot water or vinegar slows the reaction and produces a milder flavour.
The biblical parable of the mustard seed refers to Brassica nigra, which can grow into a plant over 2 metres tall from a tiny seed. Herb Cottage also sells Yellow Mustard Seeds, which are milder and better suited to American-style mustard.
